BALING-PRESS.

SPECIFICATION forming part of Letters Patent No. 434,761, dated August 19, 1890.

Application filed November 8, 1889. Serial No. 329,607. (No model.)

To alt whom it may concern:

Be it known that we, JOHN WV. BROWN and ALBERT A. GEHRT, both of Quincy, in the county of Adams and State of Illinois, have invented a certain new and useful Improvement in Bailing-Presses, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

Our invention relates to certain improve ments in presses for baling hay, cotton, excelsior, straw, and the like ,and ourinvention consists in features of novelty, hereinafter fully described, and pointed out in the claims.

Figure I is a detail side elevation illustrative of our invention. Figs. II and III are detail top views showing the parts in difierent positions. Fig. IV isa detail vertical section of the power end of the press, taken on line IV IV, Fig. V. Fig. Vis part in top View and part in horizontal section taken on line V V, Fig. IV. Fig. VI is an enlarged detail view illustrative of a part of the clutch arrangement. Fig. VII is a section taken on line VII VII, Fig. V. Fig. VIII is a transverse section taken on line VIII VIII, Fig.

' VII. Fig. IX is a detail horizontal section taken on line XI XI, Fig. X, the sliding plate closing the division-board opening. is a vertical transverse section taken on line X X, Fig. IX. Fig. XI is a section taken on line IX IX, Fig. X, the sliding plat-e being drawn back. Fig. XII is a section taken on line XII XII, Fig. IX, the plunger being down. Fig. XIII is asection taken on line XIII XIII, Fig. XI, the plunger being up. Fig. XIV isa detail view showing a portion of the upper part of the baling-chamher and illustrating the inner wall of this portion of the chamber, which serves to tuck the material after each charge has been forced forward. Fig. XIV is a similar view, the feed-opening being shown in addition thereto.

Referring to the drawings, 1 represents the main timbers of the press, and 2 the balingchamber.

3 represents the t13.V6l'S6l;4, the pitman, and 5 the power gearing or wheels that transmit the motion to the traverser. We have shown for this purpose a pair of cog-wheels,

Fig. X.

to which motion would be imparted in any ordinary manner, and to which the outer end of the pitman is connected, as shown at 6, Fig. V.

7 represents a hopper placed over the baling-chamber, the forward or inner end of which incloses the opening 7,through which the material passes into the baling-chamber. This hopper consists of sides 8 9 and closed ends 10 and ll. (See Figs. II and III.) The parts 8 of the sides are placed at an inclination, as shown in Figs. II and III, and the parts 9 of the sides fit and work within the parts 8,

.and are held outwardly againstthe parts 8 by means of a suitable spring or springs 12.

13 represents rods connecting the end piece 11, and consequently the parts 9 of the sides, to extensions 14. of the traverser, the rods being hooked into the extensions, as shown at 15, Figs. II and III, and being turned upward at their outer ends, as shown 16, Fig. I, to engage the end piece 11. It will thus be seen that as the traverser goes back and forth the parts 9 of the sides of the hopper and the end piece 11 will be carried back and forth with the traverser. Then the traverser is in its inner position, these parts of the hopper are in their outer position, as shown in Fig. III. The material for the next charge is, while the parts are in this position, thrown into the hopper, and then, as the traverser recedes, carrying this movable part of the hopper with it, the material is compressed both longitu dinally and transversely of the press by the forward movement of this part of the hopper and by the lateral contraction of the parts 9 of the sides being forced inwardly by bearing against the inclined fixed parts 8 of the sides. We thus produce a very cheap and effective means for condensing the material before it passes into the baling-chamber. As the traverser reaches the limit of its backward movement, the condensed material is forced into the baling-chamber by means of a plunger 19,10- cated over the opening of the baling-chamber, through which the material passes, and which has a vertical stem 20, connected toits base at 21, and by means of braces 22. The base 19 is of sufficient size to snugly fit in the opening 7 of the baling-chamber. The stem 20 is guided by means of vertical standards or posts '23, which are slotted to receive friction-rollers 24, secured to the stem. The plunger is operated at the proper time to force the condensed ma terial into the baling-chamber by means of a lever or levers 25, connected by links 26 to the plunger. The levers are pivoted at 27 to the frame of the press, and their lower ends are provided with friction rollers or projections 28, that fit in canrgrooves 29 made in the faces of the gear-wheels 5, the cam-grooves being so shaped that the plunger will be held suspended at the proper time, and at the proper time forced downward to feed the condensed material from the hopper into the baling-chamber. lVhen a bale has been completed, or, liLlLllQl',Wl18Il a suificient amount has been pressed to form a bale, a division-board is automatically inserted by the following means:

30 represents a horizontal shaft suitably journaled to the frame of the press, and on the outer end of which is a bevel gear wheel or pinion 31, meshing into a similar bevel gear wheel or pinion 32, (see Figs. I, II, III, and V,) this last-mentioned pinion being loosely mounted on the outer end of a short shaft 33, which passes through the journal-bearing 34 of one of the wheels 5. (See Fig. V.) On the inner end of this shaft 33 is a disk 35, provided with a projection 36, (see Fig. V1,) fitting in a notch 37 of the hub of the wheel 5, the shaft being thus connected to the wheel 5 and driven continuously thereby.

On the shaft 33 is a fixed collar 36 and a sliding collar 37. The sliding collar is provided with a projection 38, adapted to fit in a notch or recess 39 in the hub of the wheel 32, so that at the proper time the wheel 32 may be connected to and revolved by the shaft 33, it being understood, of course, that the sliding collar 37 is connected to the shaft so as to revolve with it--as, for instance, by means of a feather and groove, as shown in Fig. VII. \Vhen it is desired to produce this connection between the shaft 33 and the wheel 32, so as to revolve or operate the shaft 30, the collar 37 is moved outwardly by means of a lever 40, pivoted at 41 and connected at its inner end to the collar 37, preferably by means of pins fitting -in circumferential grooves of the collar, as shown in Fig. V. By forcing the upper end of the lever 40 inwardly its outer. end will move outwardly, carrying the collar 37 into engagementwith the wheel 32, as shown in Fig. VII. The shaft 30 will now be turned until the collar 37 is again moved out of engagement with the wheel 32, and this is automatically accomplished by a cam 42 on the fixed collar 36 coming against a horn or projection 43 on the lever 40, which will move the lower end of the lever inwardly again,tl1ns shiftingthesliding collar, as shown in Fig. V, the cam 42 having an inclined inner face, which, when it comes against the horn 43, will accomplish this movement of the lever. The horn 43 and cam 42 are also shown in Figs. VII and VIII. The forward end of the shaft 30 has upon it a crank 44, (see Figs. II and 1H,) and upon this crank is a friction roller or projection 45. g

46 represents one of the division-boards, which is placed at one side of the pressthe side having the shaft 30-011 a rail 47, the rail having a rib fitting in a' groove in the lower edge of the division-board, as shown in Fig. I. The division-board is held on the rail 47 and prevented from tipping over by means of a short rail 48, similar tothe rail 47, located at the top of the press. Now at the proper time for the insertion of a division-board the upper end of the lever 40 is pressed inwardly, causing the turning of the shaft 30, as described, and a division-board is thus forced into the baling-chamber along the rail47, and when the movement is made and the crank 44 is returned to its position shown in Fig. III the cam 42 comes against the horn 43 of the lever 40 and forces the collar 37 out of engagement with the wheel 32 again, and the movement of the shaft 30 stops, and, another division-board being placed on the rail 47, the operation is ready to be repeated.

It is desirable that the opening 50 in the side of the baling-chamber through which the division-boards enter the baling-chamber should be closed except when the divisionboards are entering. To accomplish this we locate a sliding plate 51 in the opening 50, which is provided with lugs 52, engaged by a cam 53 on the shaft 30. (SeeFigs. IX, X,and XI, also Fig. I.) The cam is so formed that the sliding plate 51 will be moved back to the position shown in Fig. XI to allow the passage of the division-board, and then, after the division-board has entered the chamber, the cam forces the plate 51 back and closes the opening again. This opening is thus closed and opened entirely automatically.

represents a metal plate located at the top of the baling-chamber on the inside and just in the rear of the feed-opening. Its function is to tuck down the material that overhangs the traverser each time the traverser recedes. The plate forms the upper wall of the baling-chamber at this part, and it will be readily understood how its elasticity will allow it to yield upwardly as a charge is forced beneath, and when the traverser recedes it will spring down again, and its bond 61 will tuck or fold the overhanging material down so as to be pressed forward in advance of the next charge. This bend 61, in addition to folding the material, also serves to strengthen the plate 60.

We claim as our invention- 1. In a baling-press, the combination,with the billing-chamber and a hopper, of a plunger having a stem, vertical standardsby which the stem is guided, having slots receiving projections on the stem, the power-wheels having cam-grooves, the swinging levers pivoted to the frame, the links connected to the upper ends of the levers and to the stem of the plun ger, and the projections on the lower ends of the levers working in the cam-grooves, substantially as described.

2. In a baling-press, the combination of the traverser, the baling-chamber, and a means for inserting the division-boards, consisting, essentially, of a shaft, a clutch arrangement for operating the shaft, and a crank-arm on the shaft for forcing the division-boards into the baling-chamber, substantially as and for the purpose set forth.

3. In a baling-press, the combination of the traverser, a baling-chamber, and means for forcing the division-boards into the balingchamber, consisting, essentially, of two shafts connected by a gearing, a sliding collar adapted to clutch said gearing,-a connection between the power-Wheels of the press and one of said shafts, a lever for operating said collar, a crank-arm on said shaft for engaging the division-boards, and a rail for supporting the division-boards, substantially as and for the purpose set forth.
